Ripper Street (10/9c, BBC America): A fourth season of the evocative Victorian-era crime drama opens with Edmund Reid (Matthew Macfadyen) having washed his hands of Whitechapel, while his former partner Inspector Bennet Drake (Game of Thrones' Jerome Flynn) has been promoted to try to keep the peace amid an anti-Muslim uprising—how timely. But Reid is lured back to service to try to keep an old friend from hanging, while Capt. Jackson (Adam Rothenberg) is similarly attempting to rescue his wife Long Susan Hart (MyAnna Buring) from the executioner. The first episode takes its time setting up what appears to be a season-long arc.
